Express as a trinomial
(2x-5)(3x-4)

6x²-23x+20

Step-by-step explanation:

2x*3x-2x*4-5*3x-5(-4) calculate multiply

6x²-8x-15x-20 collect like terms

6x²-23x+20

hope it helps

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
